To all whom it may concern:

Be-it known that I. 'ILILIAM C. MATTHIAS, a cit-izen of the United States. and a resident of the city of Reading. in the countv of Berks and State of Pennsylvania, havev invented Sewage-Disposal Apparatus, of which the following is a specification.

My invention relates to sewage purification and particularly to( sprinkling filter apparatus therefor. t

The partially purified sewageV has heretofore been discharged upon lter beds by distributed through suitable conduits connected with a. so-called dosing apparatus" interposed between the distributing conduits and the main supply conduit.

My invention consists in improved dosing apparatus adapted to automatically provide an intermittent varying-head fiow of sewage to the sprinklers, ashereafter fully described ings illustrating' a referred embodiment of the invention; ant the novel features are specifically pointed out in the claims.

.Figure 1 is a diagrammatic view showingv the general arrangement of the dosing apparatus and its relation to the filter beds and sprinklers; and' Fig. 2 isa corres bonding ele.- line 2-2 of Fig. 1.v Fig. 3 is a much enlarged partial plan view showing the valve operating mechanism. Fi 4 is an elevation of the same looking in t e direction of the arrow 4,'Fig. 3, showing the valve-operating floats in raised osition and the valve operating mechanism 1n corresponding position; the view of said mechanism being across-section on the line 4-4 of Fig. 3, but the position of the Weighted `arms which are cut away, being indicated in dotted lines. Fig. 5 is a partial elevation similar to Fig. 4, but showing the valve operating mechanism inthe different positions which automatically result from the fall of the main float. Fig. 6 shows separately the cushion stop device preferably einployed to control the rotary movement of the valve-operating shaft.

tei', are carried as indicated by riser pipes 4, 4, connecting with a system of distributer pipes 5, 6, 7, leading to a main distributer conduit 8. The dosing apparatus which contiols the flow ofthe effluent to thesefsprinklers and which constitutes my invention, is interposed between the supply conduit 1 and the main distributer conduit 8. This dosing apparatus comprises a suitably elevated tank or vreservoir 10, which as shown is divided into three compartments, namely a main dosing compartment 11, a storage compartment 12, and an overflow compartment 18, arranged to receive the overflow from compartment 12.. Leading to the compartments 12 and 11 respectively are parallel conduits 14 and 15, the former 1-l) connecting to a branch 16 of the main supply conduit 1, and the latter (15) communicating through transverse connections 17 and 1S with the storage conduit 14, and through another connection 19 with the main distributer conduit S. The connections 17, 18 and 19 are provided with separate valved-chambers 21, 22 and 23, each having a butterfly valve, marked respectively 24, 25 and 26, provided with a suitable 'exterior crank 27, 2S or 29, for operating the same. An additional connection 3() affords communication between the overf low compartment 13 and the. main distributer conduit S.

The flow from the main supply conduit 1, through the -reservoirl'lO to the main distributer 8 and theco'nnectedsprinklers, is controlled by an automatic ...valve-,operating mechanism' which is adapted t-oproduce an 'intermittent varying-head discharge from 'impart a rocking movement to a 'suitably mounted rotary shaft 38 liaying a' valveoperating arm 39 with connections 40 and 41 Y to the cranks 28 and 29 of the valves'Q and 26, asV indicated. The shaft 38 is rovided with a fixed arm 42 havingan' -atjustahle counterbalance weight 43, and with a fixed crank-arm 44, whicii latter is acted upon by the rise and vtall of the float 36, als follows: The upper end of the float rod 37 is connected to a loosely mounted arm 45 on theshaft 3S, so that said arm is freely raised and lowered with the float. This arm is provided with a laterally projecting pin 4.6, which is adapted to conta-ct with an adjacent loosely shorter arm, which projections are adapted to contact with the opposite edges of the fixed crank-arm 44, 'at certain portionsof the swing of the lever, so as to turn the shaft 38 in one direction or the other and thereby reversely operate the two connected valves 25 and 26; this turning action of the lever upon the shaft being ellected in both directions by thelall of the weighted end of the lever 47, which swinging end is merely moved to one' side or other or' the dead center by the rise or fall of the float 36 causing intermittent con-,-

the shaft 38 under the impact of the falling weight 4S of the lever 47, is positively limited in each direction as shown, -by providing stop-arms 52 and 53'on said. shaft, adapted to seat against adjustably iixedstops 54; and to avoid theobjectionable jar otherwise liable to occur l employ also a hydraulic cushion of well-known construction as indicated in Fig. 6, the slotted plunger head 55 of which is connected to a ixed arm 56 on the shaft so that the stopJarms 52, 53 will be easily and quietly seated by the cushioned movement-otl the plunger.

To prevent unintended turning movement ol the shaft 3S d ue to possible binding or undue friction oic the loose float-connected arm 45, l employ a supplemental weighted arm 60 (see Fig. 5) fixed to the Vshalt 38 so 'as to resist such a premature turning movement though adapted to coperate with the weighted lever 47 when the latter is operating by its fall to normally turn the shaft (see Fig. 4).

Before further referring to the oint o eration oi the valves 25 and 26 l -will briefly describe the separate means provided as shown for correspondingly operating the additional valve 24. For this purpose I employ a second riser pipe forming a separate lloat chamber 61, which is connected with the float chamber 35 and is provided with a float 62 on a collared rod 63, which latter is connected to one end ota valve operating lever 64, pivoted at 65 and suitably connected at Vits o posite end to the crank 27 of valve 24;

said ever 64 being suitably balanced so as to be readily operated by the-float to turn-the sanftes valve 24 as determined by the in the oat chambers.

Themain supply conduit is :always in communication with the storage compartment 12 of reservoir 10, but its communication with the dosing f compartment 11 and with 'the main distributer con duit 8," and the communication et' the storage and ldosing compartments with said conduit 8, are automatically regulated bythe iloatoperated-valve mechanism so as to i'ntern'iitteutly cut-oil the flow to the conduit 8, andaleo to vary the head of such iow so as to gradually reduce the spread of the sprinklerdischarge thereby fully utilizing the 'filter bed area. Starting at a time when there is no discharge from the sprinkler nozzles, the oat 62 will be in lowy ered position closing the valve 24, and the float 36 will also be lowered with its connected valve operating mechanism in the positions indicated inFig. 5, valve 25 -being open and valve 26 closed. The sewage now ilows into both the dosing and storage compartments (11 and 12),I the level being the same in both since they are connected through valve 25. As the liquid rises valve 24 is head of liquid opened by the float 62, and as the compartments 11 and 12 are filled the iloat 36 is 'fully raised, lifting the connected arm 45 from the position-indicated in Fig. 5 until its pin '46 engages the loosely mounted lever 47 and swings the Weighted end .'48 thereof past. the dead centerso that it will fall to the position indicated in Fig. 4,'which falling movement, by

engagement of the lever pin 50 with the fixed crank arm 44, turns the shaft 3 8 and its valve operating arm 39 as shown in Fig. 4,

thereby simultaneously opening the valve 26 and closing the valve 25. The liquid now flows freely from' the latter including vany Voverliow from com artment 13, being also supplemented as in icated by the direct flow from the main 1, valves24 and 26 being open andl valve 25 Closed. As the liquidv is drained from the reservoir compartments the head on the'sprinkler nozzles gradually falls,

4from a maximum of say seven feet (indicated at a Fig'. 2), to three and a half feet (b), When the valve 24 is closed by the corresponding fall ofthe float 62 cutting off communication between the main supply conduit 1 and the sprinklers and turning the di rect flow into the storage com artment 12 to refill the latter. The gradual y reducing disl charge from the dosing compartment 11 to the nozzleshowever continues until the head on the .nozzles reaches the determined minin mum (c`Fig. 2),` when the valve operating mechanism Will he returned to the position indicated in Fig. 5 by the reverse operation of the falling lloat 36, through the Weighted le- .ver 47 ,upon the rocker'shaft 38, thereby re-' turningto the starting conditions by ,Closing valve 26 and o yening valve 25. y

' The cycle or operations described will be automatically repeated indefinitely, the time takenfor each cycle and the Vintervals of rest being of course changeable to some degree by variations in the flow, but the desired uniform and satisfactory automatic distribution of the sewage being practically secured at all times.
